Objective:To clarify the effects of simple subtalar fusion on distribution of plantar pressures.Methods:A retrospective study was conducted to analyze the 19 patients who had undergone simple subtalar fusion between January 2006 and December 2020 at Department of Orthopedics, Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine. There were 13 males and 6 females with an age of (42.1±11.8) years and a duration of disease of 1.7 (1.0, 2.0) years. Another 14 normal subjects were recruited as normal controls [7 males and 7 females, with an age of (25.0±1.9) years]. The data of plantar pressure distribution were detected and analyzed by a Belgian Footscan? plantar pressure tester. The affected and healthy sides of the patients were compared with those of the normal group to analyze the peak pressures on different foot regions.Results:There was no significant difference in height or weight between the patients and the normal subjects ( P>0.05). The peak pressures on the first to the third metatarsal region of the forefoot and the medial region of the hindfoot of the affected foot were significantly lower than those of the normal foot in the patients ( P<0.05). The peak pressure on the forefoot region of a normal foot appeared in the third metatarsal region. In the patients, the peak pressure on the forefoot region of a healthy side shifted inward and appeared in the second metatarsal region, but the peak pressure on the forefoot region of an affected side shifted laterally and appeared in the fourth metatarsal region. The peak pressure on the midfoot of an affected side [(4.38±2.17) N/cm 2] was significantly higher than that on a healthy side [(3.04±1.80) N/cm 2] in the patients ( P=0.035). The peak pressures on the medial and lateral hindfoot regions of a healthy side were (7.12±1.91) N/cm 2 and (7.98±2.03) N/cm 2, respectively, showing no significant difference ( P=0.086). The peak pressure on the lateral hindfoot region of an affected side [(10.77±4.21) N/cm 2] was significantly higher than that on the medial hindfoot region [(8.71±2.89) N/cm 2] ( P=0.009). The peak plantar pressures on the affected side shifted to the lateral side in the patients. Conclusions:Subtalar fusion can exert significant effects on the distribution of plantar pressures. Specifically, the plantar pressures shift to the lateral side of an affected foot during all the gait stages while the plantar pressures on the healthy forefoot may compensate by transferring to the medial side in the patients.

Objective:To preliminarily evaluate the lumen gain of sonodynamic therapy (SDT) mediated by sinoporphyrin sodium at carotid and femoral atherosclerotic plaque sites, and to assess whether concomitant statin use, lesion location, plaque echogenicity/type, and baseline stenosis severity modify the therapeutic response.Methods:This single-center, prospective, exploratory pilot clinical study enrolled patients with peripheral artery disease who attended the outpatient cardiology clinic of the First Affiliated Hospital of Harbin Medical University between February and September 2016. All enrolled patients received optimized oral medical therapy in combination with a single session of SDT. Vascular evaluation was performed using color Doppler ultrasound before treatment and 1 and 4 weeks after treatment. The primary efficacy endpoint was the percent change from baseline in luminal diameter stenosis at the site of the atherosclerotic plaque (%Δ) at week 4, while the secondary efficacy endpoint was %Δ at week 1. Subgroup analyses were conducted according to prior statin use, plaque location, plaque characteristics, and baseline degree of luminal stenosis.Results:A total of 24 patients, aged (70.7±2.2) years were enrolled. There were 20 (83%) males. Compared to baseline, luminal diameter stenosis at the plaque site reduced by week 4 ((50.1±1.2)% vs. (57.2±1.1)%, P<0.001), %Δ was(12.32±1.05)%; and luminal diameter stenosis also reduced by week 1 ((51.7±1.2)% vs. (57.2±1.1)%, P<0.001)), %Δ was(9.61±0.85)%. In subgroup analyses, the treatment effect on diameter stenosis was independent of prior statin use; SDT reduced stenosis in both carotid and femoral plaques; with superior efficacy observed in hypoechoic and mixed-echo plaques; and efficacy was observed across mild, moderate, and severe baseline stenosis categories (all P<0.05). Conclusion:In this single-center pilot study, SDT demonstrates therapeutic efficacy across mild, moderate, and severe stenoses, as well as in hypoechoic and mixed-echo plaques, showing potential to rapidly promote luminal gain at carotid and femoral atherosclerotic plaque sites.

Objective To investigate the status quo and its influencing factors of nurses'organizational silence in 3 Grade A general hospitals.Methods Convenient sampling method was used to investigate clinical nurses in 3 Grade A general hospitals in Xi'an from April to August 2023 by general data questionnaire,nurses'organizational silence questionnaire and hospital magnetic factor scale.Multiple linear regression was used to analyze the influencing factors of organizational silence.Results A total of 855 nurses completed the study.The total silence score of nurses was(56.33±8.55);The total score of hospital magnetic level was(107.63±12.85).There was a negative correlation between nurse tissue silence and hospital magnetic level(r=-0.318,P<0.01).Hospital magnetic level,age,job title and working time were the influential factors of nurses'organizational silence(all P<0.001),which together explained 62.60%of the variation.Conclusions The silence of nurses'tissue and the level of hospital magnetism are in the low-medium level.Nurses are younger in age,lower in professional title,shorter in nursing age and lower in hospital magnetism level,the higher the tissue age level is,the nursing managers can reduce the tissue silence of nurses by improving the hospital magnetism level.

Objective:To explore the diagnosis and clinical characteristics of multi-slice spiral computed tomography angiography(MSCTA)on acute aortic syndrome(AAS).Methods:A total of 185 patients with suspected AAS who were treated in Fuyang People's Hospital from June 2020 to July 2022 were selected,and the diagnostic results of digital vascular subtraction(DSA)were taken as the"gold standard".Before confirmation,MSCT plain scan and MSCTA examination were conducted,and the positively and negatively predictive values of MSCT plain scan and MSCTA were calculated by using four-cell table method.The area under curve(AUC)values,sensitivities and specificities of MSCT plain scan and MSCTA in diagnosing AAS were analyzed by using receiver operating characteristic(ROC)curve model.Results:As the gold standard of DSA diagnostic results,82 cases of 185 patients with suspected AAS were confirmed as AAS.The positively and negatively predictive values of MSCT plain scan were 68.35%and 73.58%,respectively.The positively and negatively predictive value of MSCTA examination were 96.30%and 96.15%,respectively.The diagnostic accuracy of MSCTA was significantly higher than that of MSCT plain scan(x2=42.092,P<0.05).The detection rates of laceration locations(ascending aorta,aortic arch and descending aorta)in MSCTA were significantly higher than that in MSCT plain scan(x2=6.788,4.000,12.974,P<0.05),respectively.ROC curve analysis showed that the AUC values of MSCT plain scan and MSCTA were respectively 0.698 and 0.946 in diagnosing AAS.Conclusion:MSCTA has a higher efficiency in diagnosing AAS,and AAS mostly includes the aortic dissection separation and aortic intramural hematoma.

Objective:To investigate the relationship between criminal’s ability to recognize facial expressions and prosocial behavior tendency, and the possible mediating role of empathy and the moderating role of social support between them.Methods:Totally 200 male criminals were surveyed with facial expressions recognition ability test, prosocial tendencies measure, interpersonal reactivity index and perceived social support scale in August 2022.SPSS 20.0 and the PROCESS macroprogram written by Hayes were used for correlation analysis, mediating and moderating effect testing.Results:Prosocial behavior tendency(79.145±12.134) was significantly negatively related with times of imprisonment(1.555±1.045) ( r=-0.227, P<0.01). Ability to recognize facial expressions had a direct effect on criminal’s prosocial behavior tendency (total effect=0.338, P<0.01), and empathy played a mediating role between them (indirect effect=0.094, P<0.01). Social support moderated the relationship between ability of recognize facial expressions and criminal’s prosocial behavior tendency ( β=0.176, P<0.01) and empathy ( β=-0.291, P<0.01), and the relationship between empathy and criminal’s prosocial behavior tendency ( β=-0.270, P<0.01). Conclusion:Facial expression recognition ability has a significant positive effect on criminal’s prosocial behavior tendency, empathy and social support play mediating role and moderating role between them.

Objective:To investigate the quality of life in children with McCune-Albright syndrome (MAS) and its influencing factors, so as to provide scientific basis for improving their quality of life.Methods:The clinical data of 31 children with MAS diagnosed (MAS group) and followed up in Henan Children′s Hospital from June 2015 to December 2021 were retrospectively analyzed.During the same period, 37 healthy age and sex-matched children at a ratio of 1∶1 were recruited as healthy control group.The children′s Quality of Life Universal Core Scale (PedsQL?4.0) was used for the investigation and comparative analysis.Statistical analysis was performed using the independent sample t test, Chi- square test and multiple regression analysis. Results:Compared with the healthy control group, the physiological function ( t=2.092, P<0.05), emotional function ( t=2.373, P<0.05) and total score ( t=2.360, P<0.05) of MAS group significantly decreased.Multiple regression analysis showed that physiological function was negatively correlated with the annual number of vaginal bleeding ( t=-2.367, P<0.05) and the age of first fracture ( t=-2.606, P<0.05). Social function was negatively correlated with the number of fractures ( t=-2.481, P<0.05). Conclusions:The overall quality of life of MAS children is low, especially the quality of physiological function and emotional function.The annual number of vaginal bleedings, the age of the first fracture and the number of fractures are influencing factors for the reduction of the quality of life of children with MAS.

Objective To study the effect of corrected TIMI frame count (CTFC) of infarction related artery on systolic function of infarct area of myocardium after primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods One hundred and six patients with AMI having undergone successful PCI in Cangzhou Central Hospital were selected, and they were divided into two groups (each, 53 cases). The standard of fast or slow flow was in accord to the CTFC of infarction related artery (IRA) measured soon after successful PCI. The patients with greater value of CTFC were enrolled in the slow flow group, while the patients with smaller such value were assigned in the fast flow group. At 6, 12, 24 and 48 hours after PCI, the venous plasma MB isoenzyme of creatine kinase (CK-MB) level was measured. And at 1 week, 1 month and 3 months after PCI, the left ventricular ejection fraction (LVEF) was measured by cardiac ultrasound, and the levels of radial strain (RS) and longitudinal strain (LS) of the infarct area were measured via speckle tracking imaging (STI). The differences in CTFC, CK-MB, RS and LS between the two groups were analyzed, and the correlations between the strains and CTFC, CK-MB were analyzed by Pearson linear correlation method. Results After successful PCI, the CK-MB of fast flow group was higher than that of the slow flow group at 6 hours. However, the CK-MB of slow flow group was higher than that of the fast flow group after 12 hours, appearing separate phenomenon, and the statistical significance occurred beginning from 24 hours after PCI (U/L, 24 hours:98.43±11.65 vs. 86.43±18.97, 48 hours:51.09±8.94 vs. 49.80±6.92, both P<0.05). CTFC in fast flow group was significantly lower than that of slow flow group (frame: 22.69±4.83 vs. 26.14±5.67, P < 0.01). After 3 months of follow-up, LVEF in fast flow group was higher than that of the slow flow group, but the difference had no significance (P > 0.05). RS and LS in fast flow group were higher than those in slow flow group, and the statistically significant difference appeared from 1 month after PCI (1 month RS:29.74±6.66 vs. 26.86±5.61, LS:-16.37±3.91 vs. -15.27±3.22, 3 months RS: 30.03±6.31 vs. 27.63±5.67, LS: -17.74±3.96 vs. -15.75±4.17, all P < 0.05). Pearson linear correlation showed:the strains (both RS and LS) and CK-MB had no significant relation (both P>0.05). Both RS and LS at 1 week, 1 month and 3 months were of significantly positive correlation with CTFC of each group (fast flow group:r value of CTFC and RS was respectively-0.526,-0.515,-0.532, r value of CTFC and LS was respectively-0.532,-0.541,-0.572;slow flow group:r value of CTFC and RS was respectively-0.691,-0.685,-0.702, r value of CTFC and LS was respectively-0.621,-0.584,-0.605, all P<0.01). Conclusion CTFC has some relationship with the recovery of the systolic function in area of infarct myocardium after PCI, and can be regarded as an important index to predict the long-term prognosis in patients with AMI.
